120V-230V Installation sanity check

[pbouchar]

Hi
After a couple of weeks working with the builder and researching the internet, I came to the conclusion that building a truly power universal electrics system for my boat is too costly, too heavy and take way too much space. The following diagram is what I proposed to the builder and he has accepted. This is of course a compromise. While in Europe the shore power will only be use to charge the batteries bank, the power hungry appliance will not work unless the generator is use, the other appliances will work from the inverter. My only concern now is security, how secure is this installation and how far am I from the ABCY standard. Your comments are welcome.
Thanks
Pierre

Looks like a good compromise. I have a few questions though 1) how much time are you going to spend in 230/50hz areas as opposed to 120/60? If it is not a long time frame in 230/50 areas would it be better to just use one of the adapters and not make a permanent addition to your boat. Especially if you are just using shore power for charging batteries.

Here is a link to a very good description of the different options avaialble to a cruiser by Jack Tyler on Whoosh who has been cruising Europe for a few years ntil the Euro got to strong.

Hope this helps.

You can get multi voltage input chargers. Victron and Mastervolt both do those. It would mean you only need one charger.
Many of the 110V boats that make it down here, simply install a 230>110V transformer. All the boat operates normaly. A 3 or 4KVA trany will cover most appliances and it is not that expensive.

To answer your question, we should be in europe for about 7 months until we crossed to the caribbean and from there we dont know.

Thanks for the Jack Tyler web side reference the "taylor portable transformer" might be another solution. I will send them an email to get more info on their products

On the other end, having two chargers on the boat is giving us a backup in case one charger is failing

Is this the sort of thing-a-ling, Alan?

Not bad but I would look for one where the input and output can be configured to be an isolation tranny as well as step up/down. Then you don't need a galvanic isolator.

Yep that's the sort of theing. Dang that's cheap. But he may need the 230V down to 110V if he is getting a US boat and taking it to Europe. The trany in the link is Isolating. Mostly all those kinda tranys are. Especially if they are designed for outdoor tool use.

[Whimsical]

Yes it is isolating but if it can only be 110 to 220, or vise versa, then it can only be used when wanting the conversion. If it can be set to 1:1 then it can be used all the time

Mike

P.S. It is only isolating if it aint an auto tranny. Check to be sure

heres the whole page 110V and 230V Tool and site transformers
I gotta tell you this stuff is way above my head.

Pierre's one was about 1,000 EUR so even if this didnt work as well its such a significant cost savings.
Also the yellow box looks water proof and if its designed for outdoor contruction sites it must be.

Perhaps its that thing of buying non marine equipment that happens to be of marine quality/capicity?

I do agree with check to be sure. But 99.999% sure it will be isolating. All outdoor use transformers are just for that Isolating Tx's. That is so any power tool that is not double insulated, is lifted from earth. It also means all power cords are also llifted from earth. So if one goes into a puddle of water, it can not become leathal. Or if someone accidentaly chops one through, it also does nto become leathal.
